I have looked around the JMeter documents and elsewhere on the web to try and fid out if there is a limit to the number of threads available to JMeter. I have found claims of 1000 threads, 7000 threads and others, mainly depending on system resources.
I am testing a web service and I start to run into problems at approximately 350 user threads. The main error I get is a connection refused message. To the best of my knowledge, the web service can handle the number of connections. I have set up several computers all hitting the web service and the total number of users was well over 600. I could have tried more, but I ran out of computers. What sort of error is generated when JMeter no longer has the resources to work with more threads. JMeter will run 400 plus threads in one test group, but the aggregate report shows massive numbers of errors and if I look at the results in the Tree View, I see many Connection refused messages. Altering the Rampup time does not seem to improve things either.
